ORIQN. Y., A CORPORATION OF NEW MACHINE FOR COMPRESSING DETINNED SCRAPS.

SPECIFICATION forming part of Letters Patent No. 737,427, dated August25, 1903.

Application filed December 3, 1902. Serial No. 133,756. (No model.)

T all whom t may concern:

Beit known that I, MAX LEMBERG, a citizen ofthe United States, residingin Sewaren, in the county of Middlesex and State of New Jersey, haveinvented certain new and useful Improvements in Machines for OompressingDetinned Scraps, of which the following is a specification.

In the detinningof tin scraps, tin cans, &c.,

1o the tin of the scraps is dissolved in a suitable solution by theelectric current. The remaining iron and steel scraps are then subjectedto a washing operation, so as to remove the solution adhering thereto,and then transferred to a machine for compressing the same by power intocompact bundles of rectangular or other shapes, so that it can beconveniently K shipped to the iron and steel works for being Iemelted,and so again used in industries emzo ploying iron and steel.

The object of this invention is to furnish a machine for compressing thedetin ned scraps in a compact and effective manner, said maV-` chinebeing operated by hydraulic means;

z5 and for this purpose the invention consists of a machine forcompressing detinned scraps which comprises a plurality ofreceivingboxes, stationary pluu gers, a carriage for said boxes, meansfor reciprocating said carriage 3o so as to place it vertically belowthe plungers, a platform for supporting said boxes, hydraulic means forraising the platform so as to move the boxes over the plungers, meansfor locking the boxes after the scraps have been compressed to theproper degree, means for delivering the compressed scrap through thelower ends of the boxes, and means for removing the compressed scrap.

The invention consists, further, of certain 4o details of constructionand combinations of parts, which will be fully described hereinafter andfinally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved apparatus for compressing detinnedscraps, showing the boxes in position for receiving the scrappreparatory to compressing the same. Fig. 2 is a plan view, partly inhorizontal section, on line 2 2, Fig.

Ascrap is delivered.

Figs. 6, '7, and 8 are vertical transverse sec- 6o tions through theplatform and `lower part of the boxes, showing the same, respectively,in the act of final compression of the scrap, iu the act of lifting theboxes, and in the act of removing the compressed .scraps from the o5lower ends of the boxes.

Similar letters of reference indicate corre- 'sponding parts.

Referring to the drawings, A represents a platform on whichV thedetinned and washed 7o Inline with the platform is arranged ahopper-shaped portion,which is made in the shape of a gridiron, so as topresent as many openings as there are receivingboxes for compressing thescrap. Below the hopper B are arranged the receiving-boxes O, aplurality of which is arranged sidewise of each other. In the drawingsthree pairs of receiving-boxes are shown,whicl1 are placed verticallybelow the three pairs of openings 8o in the hopper B. Thereceiving-boxes are made of stout boiler-iron and reinforced at thecorners by angle-irons riveted thereto, the upper ends being somewhatcurved outwardly, funnel fashion, in line With the taperiug openingsofthe hopperB, so as to prevent scraps from falling in the spacesbetween the boxes to facilitate uthe transferring of the scraps. fromthe platform by forks into the receiving-boxes. In the spaces betweenthe 9o boxes are arranged stay-bolts t, by which the receiving-boxes arefirmly held in vertical position and mutually strengthened. Thereceiving-boxes O are open at their upper and lower ends,the lower endsresting onawheeled platform C', the wheels ofsaidplatform resting on araised plate C2, located vertically below the hopper B, said plate beingprovided with a depression or incline at one end to permit the transferofthe boxes,with their charge of detinned scraps, onto a movableplatform D at the upper endofthe piston of a hydraulic cylinder E. Thewheeled platform C is provided With as many raised portions d of squareshape as there are boxes, said raised portions fitting in the lower endsof the receiving-boxes C and closing the lower ends of the boxes duringthe compression action on the detinned scraps in the same. The wheeledplatform C is connected by a perforated cross-bar d with the hook-shapedend d2 of a piston-rod d3, the piston of which is guided in a horizontalcylinder d4, which is actuated hydraulically, being connected at itsingoing and outgoing ends with pipes d5 d, so that when the pressurefluid is permitted to enter into the cylinder d4 the wheeled platformC', together with the receiving-boxes C, is moved forward, so as totransfer the wheeled platform C and the'receiving-boxes C onto theplatform D of a vertical hydraulic cylinder E. The lower end of thehydraulic cylinder Eis connected with pipes e e', so as to o perate thepiston and raise thereby the platform D, together with thereceiving-boxes on the same, as soon as the valvefor supplying thepressure fluid is opened.

At either side of the hydraulic cylinder E is arranged an upright pillarF, which pillars are attached to a bed-plate F', that is located in aWell of sufficient depth to provide for the hydraulic cylinder E, whichis also secured to the bed-plate F. Thereby the plate D is normally ofthe same level as the raised plate material and fitting closely into therectangularA receiving-boxes C, so that the latter can be readily movedalong said heads when the boxes are raised by the action of thehydraulic cylinder E and plate D. The upper ends of the plungers F3 arealso provided with square heads F5, which are bolted to the under sideof the pillar-head F2, as shown in Figs. 1 and 4.

To the stationary he'ad F2 of the pillars F is attached a lug l, towhich is fulcrnmed an elbow-shaped lever G, the downwardly-extending armof which is made of hook shape, while to the horizontal arm anoperating-rod Ris applied. The hooking-lever Gis prefer- -ably arrangedat both sides of the head F2,

said levers serving for locking the receivingboxes when they graduallyarrive at their uppermost position, corresponding to the finalcompression of the scraps in the boxes, the

hook-shaped ends engaging elongated pins g, arranged on plates g',attached to opposite sides of the receiving-boxes. During the upwardmotion of' the receiving-boxes following the upward motion of theplatform D the elongated or iiattened pins g pass along the taperingends of the hooks, press the same sidewise until the hooks are movedover the pins, so as to engage the same and hold thereby thereceiving-boxes in raised position for permitting the return of theplatform D without the boxes.

To opposite sides of the wheeled platform C are pivoted spring-actuatedlocking-levers H, which are recessed at their upper ends and adapted toengage with outwardly-projecting stops h, that are attached to outeropposite sides of the receivingboxes C, as shown clearly in Figs. 6, 7,and 8. The levers H engage automatically the outwardlyprojecting stops hafter the receiving-boxes are locked by and suspended from the hooks g,so as to support the receiving-boxes at some distance from the platformD, as shown in Fig. 7, and permit thereby the continuation of thelifting motion of the platform with the receiving-boxes, so that theheads of the plungers will force the compressed scrapblocks through thelower open ends of the receiving-boxes, as shown in Fig. 8. As soon asthe receiving boxes are locked by the spring-actuated levers H skids orsleds provided with arched ends are placed in position on the platformof the carriage below the lower ends of the receiving-boxes, said skidsbeing shown in perspective View in Fig. 5a and adapted to receive thecompressed scrapblocks and to be easily removed with the scrap-blocksbefore the return motion of the platform takes place. When the platformD IOO arrives at its lower or normal position, the

. by means of forks, into the receiving-boxes C until they are nearlyiilled up. The receiving-boxes are supported by and fit on the raisedportions d of the'wheeled platform C. When the receiving-boxes arefilled with scrap, the piston of the hydraulic cylinder is operated byopening its supply-valve, so that the wheeled platform, with the chargedreceiving-boxes, is moved ,over onto the platform D, attached to thepiston-rod of the vertical hydraulic cylinder F.. The wheeled platformis arrested by a stop -pin p of the platform D, as shown clearly in Fig.3. The valve for supplying the pressure fluid to the vertical cylinder Eis then opened, so that IIO the piston of the same,'platform D, wheeledplatform, and'receiving-boxes are raised in upward direction, so thatthe receiving-boxes pass over the lower square ends l?4 of the plungersF3, by which the scraps are gradually compressed until cubical blocksare produced. During the upward motion of the receiving-boxes C the pinsg on the opposite sides of the same pass over and are engaged by thelocking-hooks G, so that the receivingboxes are suspended from saidhooks. The platform D is then lowered by reversing thepressure-fluid-supply valve until the upper recessed ends of the pivotedand spring-actuated levers l-I engage the stops h on the lower ends ofthe receiving-boxes, as shown in Fig. 7. The engagement of the leverswith the stops takes place automatically. The valves of the hydrauliccylinder E are again re versed, so that an upward motion is againimparted to the platform D, whereby the receiving-boxes are lifted bymeans of the levers H engaging the stops h, so that the plungers forcethe compressed scrap-blocks at the lower ends of the receiving-boxes indownward Vdirection onto the skids, which are placed below thereceiving-boxes before the lifting motion of the platform with levers His commenced. As soon as the compressed blocks clear the receiving-boxesand are placed on the skids the latter are removed with the blocks bythe attendants by means of suitable tools. During the downward motion ofthe blocks until they clear the lower ends of the receiving-boxes thelatter are supported on the lower ends of the levers H, as shown inFigs. 7 and S. The upper ends of the receiving-boxes are then releasedfrom the suspension-hooks, so that they are permitted to slide down onthe heads of the plungers, the locking-levers l-I being removed from thestop-lugs for this purpose. The platform D, with the receiving-boxes, isthen lowered by reversingthe motion of the valves of the Verticalcylinder E until they arrive in position shown in Fig. 3. In thisposition the wheeled platform is connected to the hooked end d2 of thepiston-rod of the horizontal hydraulic cylinder d4 and the platform withthe boxes thereon moved in backward direction by proper manipulation ofthe valves until it arrives with the boxes on the platform C2 below thehopper B ready for receiving the next charge of scraps.

By the machine shown in the drawings the scrap-blocks are simultaneouslyformed by the operation of the machine by the hydraulic action of thetwo cylinders d4 and E. The scrap-blocks are then tied together by wireand shipped to the mill for being melted to be used in industries usingiron and steel.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
